Definitions
- the invention relates generally to cordless telecommunications systems, and particularly to supporting TCP/IP services in a cellular radio access network connected to a telecommunications network offering TCP/IP services.
- WO-A1-9710684 discloses a messaging system for providing teleservices for facsimile and short massages in a DECT system.
- UMTS Universal Mobile Communication System
- FPLMTS Future Public Land Mobile Telecommunication System
- IMT-2000 International Mobile Telecommunication 2000
- ETSI European Telecommunications Standards Institute
- ITU International Telecommunication Union
- UMTS Like all mobile communications systems, UMTS produces cordless data transmission services to mobile users.
- the system supports roaming, in other words, UMTS users can be reached and they can make calls anywhere, as long as they are located within the UMTS coverage area.
- UMTS is anticipated to satisfy a wide variety of future service needs, such as high-speed data services (multimedia), and video services, such as video calls. Many future services that will be needed are difficult to envision; therefore it is not possible to optimize UMTS to one group of services only.
- UMTS must be constructed to be versatile and to permit further development. For this reason, a modular approach for the network architecture has been adopted, making it possible to implement UMTS effectively in different environments.
- UMTS is built up of two or three parts that are illustrated in Figures 1 and 2: UMTS access network 1 (or UMTS base station system, UMTS-BSS) and a core network 2, 3, 4 and 5.
- the UMTS access network will also be generally termed a radio access network in the following.
- the UMTS access network 1 is mainly responsible for things related to the radio path, i.e., it offers to the core network radio access that is needed for cordless operation.
- the core network 2, 3, 4 or 5 is a conventional or future telecommunications network modified to effectively utilize the UMTS access network in cordless communication.
- Telecommunications networks that have been contemplated as suitable core networks include the ISDN (Integrated Services Digital Network), B-ISDN (Broadband Integrated Services Digital Network), packet data networks PDN, Asynchronous Transfer Mode (ATM) networks etc., and second generation mobile communications systems, such as GSM (Global System for Mobile Communication).
- ISDN Integrated Services Digital Network
- B-ISDN Broadband Integrated Services Digital Network
- packet data networks PDN packet data networks
- ATM Asynchronous Transfer Mode
- GSM Global System for Mobile Communication
- the UMTS access network must be capable of providing support to various core networks, also those evolving in the future.
- UMTS access networks should permit connection of various radio interfaces to the core network (narrowband, broadband, CDMA, TDMA etc.).
- the UMTS access network is typically simultaneously connected to several core networks, and hence must be capable of simultaneously supporting different core networks and their subscribers and services.
- the protocol controlling the bearer services of the radio access network should be capable of setting up through the network bearer services that would best satisfy different services in each core network.
- the bearer services may comprise several parameters wherewith the service quality and the efficiency of the radio network may be enhanced service-specifically.
- a conceivable core network is the Transmission Control Protocol/Internet Protocol (TCP/IP) data network, the so-called Internet network. It is also possible that access to the Internet is provided through another core network, such as the General Packet Radio Service (GPRS) network.
- GPRS General Packet Radio Service
- the Internet makes use of a number of TCP/IP application protocols. These include:
- FIG. 3 illustrates the structure of the TCP/IP protocol.
- the application protocols are accessed through the local operating system either by a user application process or, more usually, by a user at a terminal.
- the application protocols are connected to the IP protocol layer by means of a transport layer comprising either UDP (User Datagram Protocol) or TCP (Transmission Control Protocol).
- UDP User Datagram Protocol
- TCP Transmission Control Protocol
- a feature common to all client-server interactions is the establishment of a traffic route between two application protocols or processes. All server application processes have an associated name which translates into a corresponding network-wide address.
- the translation procedure is carried out by a process known as the domain name server.
- the network-wide address consists of two parts: the network-wide IP address of the host in which the process is running and a local port number.
- the IP address is used by the IP protocol to route datagrams across the Internet to the required destination host.
- the port number is then used by the TCP protocol within the host - or UDP, if this is being used - to identify the specific process within that host to which a received message should be sent.
- An open system will include multiple clients and servers both of different types and of the same type. All servers of the same type, however, are assigned the same system-wide port number.
- the port numbers of the above-described application protocols are as follows: FTP 21, TELNET 23, SMTP 25, and WWW 80.
- a client process When a client process initiates a call to a correspondent server process, it uses as a destination address the IP address of the host in which the server is running coupled with the appropriate well-known port number of that server. As a source address it uses the IP address of its own host together with the free (unused) port number on that host. If TCP is being used, the local TCP protocol entity will then establish a transport connection between the client and server processes (using these addresses) over which the appropriate message exchanges can take place.
- the method is characterized by identifying the TCP/IP service to which the IP packet relates on the basis of the content of the IP packet, maintaining in the radio access network information on the bearer service parameters required by each TCP/IP service, setting the bearer service parameters in accordance with the identified TCP/IP service in the radio access network.
- the invention also relates to an arrangement for setting bearer service parameters in a cellular radio access network connected to a core network which is an IP/TCP network or offers a connection to an IP/TCP network, the arrangement comprising resource control means for the radio access network by means of which bearer services are reserved for the connections, and first means located at the boundary of the radio access network, initiating reservation of a bearer service for a given connection upon receipt of a first IP packet relating to the connection-
- the arrangement is characterized in that it further comprises second means maintaining information on the bearer service parameters required by each TCP/IP service in the radio accuse network, said first means being adapted to identify the TCP/IP service on the- basis of the content of the IP packet received from the core network and requesting from the resource control means a bearer service having the bearer service parameters required by the identified TCP/IP service, obtained from the second means.
- the invention further relates to a mobile station and a network unit as claimed in claims 16 and 17, respectively.
- the basic idea of the invention is that the bearer service parameters required by different TCP/IP services are predetermined in the radio access network the correct parameters for a given connection being selected by identifying the TCP/IP service on the basis of the content of the first IP packet received.
- different TCP/IP services can be handled in different ways in the radio access network and a bearer service that best corresponds to the actual needs can be established through the radio access network- This avoids any collapse in service quality that the user might experience when data is transferred through the radio access network, as can happen if all services are given the same treatment.
- the invention not only can service quality as experienced by the user be improved, but optimization of the capacity of the radio access network is also enabled when only correct-type capacity is reserved for each connection.
- the TCP/IP service is identified on the basis of the port number in the destination port field in the TCP or UDP packet in the user data field of the IP packet.
- the service quality required by the TCP/IP service can also be interpreted from the protocol field of the IP packet, which indicates whether the overlaying transport protocol is TCP or UDP, for instance. Since the protocols of the different transport layers may have completely different requirements, this information can be used for setting the bearer service parameters in the radio access network.
- the service type field of the IP packet may also be used in the same way.
- the different subscription-specific conditions in the radio access network can be taken into account in setting the bearer service parameters. An upper limit for the bit rate or price may be defined for the subscriber, for instance.
- the identifying and selection of bearer service parameters on the border of the radio access network may be carried out at the mobile station when a mobile originated connection (call) is concerned, and in the boundary region of the core network and the radio access network when a mobile terminated connection (call) is concerned.
- the primary embodiments of the invention will be described in the following as implemented in a radio access network in accordance with the precepts of the UMTS system, but the invention is not intended to be limited to the UMTS system.
- the invention is suitable for use in any radio access network that is connected to one or more core networks (telecommunications system) which is a TCP/IP network or offers a connection to a TCP/IP network.
- core networks telecommunications system
- FIG. 2 illustrates a network architecture for a UMTS access network in detail. It is to be noted, however, that this network architecture is only one of several possible alternatives.
- the network architecture shown in Figure 2 is based on a scenario according to which the functions of the UMTS access network are closely limited to radio access functions. Thus, it mainly comprises functions for radio resource control (handover, paging) and for controlling the bearer service (control of radio bearer service). More complicated modes of function, such as registers, registering functions and mobility and location management, are located in each core network.
- GRAN generic radio access network
- RAN radio access network
- IWU interworking unit
- IWU interworking unit
- the interface IWU-CN is core network-specific. This enables development of core networks and the RAN independently of one another.
- IWU may be connected to the base station subsystem BSS of a GSM network.
- IWU2 may be connected to a local exchange of an ISDN network, for instance.
- the radio access network RAN comprises a transport network TN, a radio network controller RNC, and a base station BS.
- the base stations are connected to the transport network TN, which transports the user data to the IWUs and the control signalling to the radio network controller RNC.
- All intelligence controlling the GRAN is located at the base stations (BS) and the radio network controller (RNC). As stated previously, this control is typically limited to control functions pertaining to radio access as well as to switching of connections through the transport network TN.
- the transport network TN may be an ATM network, for example.
- radio access network in this application generally refers to any radio access network and network structure that is connected to a core network.
- radio bearer service protocol (RBC).
- the bearer service is represented by means of various bearer service parameters, examples of which will be given below.
- the bearer service parameters comprise four main classes: 1) traffic parameters, 2) quality of service (QoS) parameters, 3) information parameters, and 4) content parameters.
- Peak Bit Rate PBR bit/s. The maximum instantaneous bit rate in connection with maximum burst size. Indicates the constant bit rate in the absence of other traffic parameters.
- Maximum burst size MBS bits. Gives an estimation of the maximum burst size that may be transmitted at peak bit rate.
- Frame size specification number of entries, minimum size, intermediate size(s), maximum size.
- a frame may have any size between minimum and maximum.
- requested intermediate sizes may be defined and the list defines the discrete frame sizes used, corresponding to discrete bit rates.
- Minimum bit rate MBR bit/s. The minimum bit rate required for URAN ABR traffic.
- Bit error rate BER Bit error rate of the connection.
- point-to-point/point-to-multipoint Gives the configuration of the connection in terms of point-to-point or point-to-multipoint service.
- Control the traffic consists of signalling.
- Unsynchronized traffic the traffic is not synchronized with the radio interface timing.
- Synchronized traffic Radio interface timing information is required.
- Coding Indicates the speech codec used.
- the core network 4 is a TCP/IP network or a network offering a transparent connection to a TCP/IP network.
- a network element or function e.g. IWU3
- the connection set up through GRAN is a transparent "tube" that transfers the IP packets from the boundary of GRAN (e.g. IWU3) to a MS and vice versa.
- the actual client host machine is thus connected to the MS.
- the adaptation function or network element e.g.
- the adaptation function IWU3 inserts the IP packets into the user data field of the protocol data units (e.g. ATM cell) used on the GRAN connection and sends them across the GRAN.
- protocol data units e.g. ATM cell
- Such a function or network element at the boundary of GRAN is furnished with a feature wherewith it can identify TCP/IP service on the basis of the content of the IP packet and, on the basis of the identification, request from the RNC a bearer service that meets predetermined bearer service parameters.
- Various information in the IP packet may be employed for identification of TCP/IP service.
- Value 6 in the IP protocol field in the IP packet indicates that the protocol of the overlaying transport layer is TCP.
- value 17 in the protocol field in the IP packet indicates that the protocol of the overlaying transport layer is UDP. It is possible to use this information as such for selecting the bearer service parameters. For example, it can be deduced from the fact that UDP is identified that the user does not require reliable transport (as there are no retransmissions on the transport layer). For this reason, the bearer service parameters predetermined for UDP could for example contain a lower frame loss ratio (FLR) and lower delay than TCP parameters. Identifying of UDP and TCP is not sufficient, however, for optimizing higher level services.
- FLR frame loss ratio
- the type of service field in the IP packet defines various properties required of the connection: high reliability, high throughput, short delay, and low priority level. This information can also be used for selecting bearer service parameters for the GRAN connection.
- the user data field in the IP packet contains a TCP or UDP packet. Both a TCP packet and a UDP packet contain a destination port field; the port number contained in this field may be used for identifying the most common services.
- the port numbers of the above-described application protocols are the following: FTP 21, TELNET 23, SMTP 25, and WWW 80.
- mapping of TCP/IP services to GRAN bearer service parameters will, however, be described by means of examples utilizing several of the above-described methods simultaneously, thus enabling better optimization.
- TCP protocol field of the IP packet
- IP service type field high throughput.
- predetermined GRAN bearer service parameters are selected for the identified FTP service:
- PBR 64000 bit/s
- SBR 32000 bit/s
- MBR 16000 bit/s
- PBR 1000 bit/s
- SBR 500 bit/s
- MBS 2000 bit/s
- MBR 0 bit/s
- TCP protocol field in the IP packet
- IP service type field low priority/maximize throughput.
- predetermined GRAN bearer service parameters are selected for the identified WWW service:
- any other appropriate mapping of the bearer service parameters to the TCP/IP services may naturally be used.
- subscriber-associated data relating to the subscription
- subscriber data may be used to determine the bearer service parameters. For example an upper limit for the price or bit rate may be defined in the subscriber data.
- the subscriber data is checked and taken into account in setting up the bearer service.
- the subscriber data may be available from an internal database of GRAN, but typically it must be requested from an external database located for example in the core network, such as a GSM home location register HLR.
- a first IP packet relating to a given connection is received by a function, device, or network element located at the boundary of GRAN (step 40, Figure 4) and having the feature in accordance with the present invention.
- the invention can be implemented from the mobile station MS, which receives the packets from a peripheral device or from its user application.
- a mobile terminated connection is involved, the invention can be implemented in the boundary region of the core network and the radio access network. Let such an element or function be IWU3 in Figure 2, in which situation the first packet relating to the terminating connection is received from a TCP/IP core network.
- IWU3 analyzes the IP protocol field of the IP packet, step 41. If the value of the IP protocol field is not 6, IWU3 identifies UDP as the protocol of the transport layer and fetches from its database the GRAN bearer service parameters defined and stored for UDP, step 45. If the value of the IP protocol field is 6, IWU 3 identifies TCP as the protocol of the transport layer. Thereafter, IWU3 examines whether the value of the destination port field of the TCP packet, which is in the user data field of the IP packet, is 21, step 42. If this is the case, IWU3 identifies FTP as the application protocol and fetches from its database the GRAN bearer service parameters defined and stored for FTP, step 46. If the value of the destination port is not 21, the routine proceeds to step 43.
- IWU3 examines whether the value of the destination port field of the TCP packet is 23. If this is the case, IWU3 identifies Telnet as the application protocol and fetches from its database the GRAN bearer service parameters defined and stored for Telnet, step 47. If the value of the destination port is not 23, the routine proceeds to step 44.
- IWU3 examines whether the value of the destination port field of the TCP packet is 25. If this is the case, IWU3 identifies SMTP as the application protocol and fetches from its database the GRAN bearer service parameters defined and stored for SMTP, step 48. If the value of the destination port is not 25, the routine proceeds to step 49. In step 49, IWU3 presumes the application protocol to be WWW and fetches from its database the GRAN bearer service parameters defined and stored for WWW, step 48.
- IWU3 forms a connection establishment message in accordance with the RBC protocol, containing the fetched bearer service parameters.
- the message is sent over GRAN to RNC.
- RNC sets up the requested bearer service across GRAN between IWU3 and the called MS.
